> Sometimes it is very difficult to provide `TypeInformation` manually, in case some extraction
fails or is not available. {{TypeHint}}s should be the preferred way but this methods can
ensure correct types.
> I propose to add all built-in Flink types to the {{Types}}. Such as:
> {code}
> Types.POJO(MyPojo.class)
> Types.POJO(Map<String, TypeInformation>)
> Types.GENERIC(Object.class)
> Types.TUPLE(TypeInformation, ...)
> Types.MAP(TypeInformation, TypeInformation)
> {code}
> The methods should validate that the returned type is exactly the requested type. And
especially in case of POJO should help creating  {{PojoTypeInfo}}.
> Once this is in place, we can deprecate the {{TypeInfoParser}}.
